Applicationflled July 27, 1914. Serial No. 853,561.

To all whom it may concern:

Be it known that we, SAMUEL E. JACKSON and .ARTHUR P. BARNES, citizens of the United States, residing at Great Bend, in the county of Barton, State of Kansas, and at West Mineral, in the county of Cherokee, State of Kansas, respectively, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in water heaters, and an object thereof is the provision of a water heater which comprises a pair of concentric shells between which a water chamber is formed, the shells being readily detachable when it is desired to remove sediment from the heater.

A further object of this invention is the provision of a water heater which comprises an inner and an outer shell forming a water chambertherebetween, the outer shell having an inwardly extending flange at one end for engagement against the adjacent end of the inner shell to close one end of the water chamber, and the inner shell having an outwardly extending flange at its other end for engagement against the other end of the outer shell, to close the opposite end of the water chamber.

A still further object of this invention is the provision of a water heater of this character, in which the outwardly extending flange of the inner shell projects beyond the outer periphery of the outer shell, and the inner edge of the inwardly extending flange of the outer shell projects beyond the inner periphery of the inner shell, the outer shell being provided with an annular rib on its outer periphery adjacent its free edge, and

the inner shell having an inwardly extending rib on its inner periphery adjacent its free edge, the adjacent ribs and flanges being adapted to receive bolts whereby the shells may be secured together, with the free edge of each shell tightly engaged against the inner face of the flange of the other shell.

With these and other'objects in View, our invention consists in the novel construction,

combination, and arrangement of parts, to

be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, which illustrates a vertical sectional vien of our improved water heater.

Referring more particularly to the drawing, the numeral 1 designates the outer shell and 2 the inner shell of'our improved water heater, the shells being arranged in concentric relation with the other thereby formmg a water chamber 3 therebetween. The water heater is arranged within a combustion chamber or jacket 4, which is of greater diameter than the heater, whereby a combustion passage 5 is formed between the periphery of the heater and the wall of the combustion jacket. same length, and the inner shell 2 is provided at its upper edge with an outwardly extending annular flange 6, which is adapted to engage against the upper edge of the outer shell and to the periphery of the outer shell. The outer shell 1 is provided at its lower edge with an inwardly extending annular flange 7, which is adapted to engage against the lower edge of the inner shell and also projects inwardly slightly of the inner periphery of the inner shell. Gaskets 8 are preferably interposed between the upper edge of the outer shell and the lower face of the flange 6, and between the lower edge of the inner shell and the upper face of the flange 7, to provide tight joints between the flanges 6 and 7 and the free edges of the shells.

Formed on the inner periphery of the inner shell adjacent its lower edge is an in-' wardly extending rib 9 and formed on the outer periphery of the outer shell adjacent its upper edge is a rib 10, the ribs 9 and 10 having openings 11 formed therein and the projecting portions of the flanges 6 and 7 having a similar series of openings 12 formed therein, the openings 10 and 12 in the ribs and flanges being arranged in vertical alinement to receive fastening bolts 13 by means of which the shells are connected together, the nuts 14 serving as means whereby the free edges of the shells upon which the gaskets 8 are mounted may be tightly forced against the opposing faces of the flanges, to provide water tight joints be tween the shells whereby leakage of water from the chamber 3 is prevented. Extending through the wall 4: of the combustion jacket and projecting within the outer shell 1 at its lower end is an inlet pipe 15, and an outlet pipe 16 projects through the wall 4 and into the outer shell adjacent its upper end, the water entering the chamber 3 through the inlet pipe and flowing up- The shells 1 and 2 are of the project slightly beyond will be seen that We have provided a water heater in which the greatest possible'heating space is provided to the particles of combustion passing upwardly within the combustion jacket, the heater comprising merely two concentric shells which may be quickly connected together to provide a water chamber therebetween, and which may be readily disconnected when it is desired to clean sediment from the water chamber.

Having thus fully described our invention, what we desire to claim and secure by Letters Patent is A water heater of the character described, comprising an outer shell formed at one end with an inwardly extending annular flange projecting from one extremity of the shell, inlet and outlet pipes entering said outer spaced from shell and supporting it, an inner shell concentric With the outer shell but having an exterior diameter greater than the interior diameter of the first named flange on. the outer shell, said inner shell at one end having an inwardly extending annular flange and at its opposite end an outwardly extending flange overlying the adjacent end of the outer shell and extending over the outwardly extending'flange of the outer shell, and fasthe adjacent end of the shelltening means passing through the fianges of the outer and innershells and detachably engaging the outer and inner shells with each other.

In testimony whereof we hereunto afiix our signatures in the presence of two witnesses.
